• This schematic diagram may be modified at any time

• Important safety notice:

Components identified by 

 mark have special characteris-

tics important for safety.
Furthermore, special parts which have purposes of fire-retar-
dant (resistors), high quality sound (capacitors), low-noise
(resistors), etc are used.
When replacing any of components, be sure to use only
manufacturer’s specified parts shown in the parts list.
 

• In case of AC rated voltage Capacitors, the part no. and val-

ues will be indicated in the Schematic Diagram.
AC rated voltage capacitors:
C5700, C5701, C5702, C5703, C5705, C5709
 

• Resistor

Unit of resistance is OHM [

Ω

] (K=1,000, M=1,000,000).

 

• Capacitor

Unit of capacitance is 

µ

F, unless otherwise noted. F=Farads,

pF=pico-Farad.
 

• Coil

Unit of inductance is H, unless otherwise noted.
 

•

REF is for indication only.
 

• Voltage and signal line

• For EE/GS only

• For PH only

Voltage Selector switch.

Open/Close switch ( ).
